...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 4 AM EDT
SATURDAY...

* LOCATIONS...The tidal portions of the Delaware River down to
  the Commodore Bay Bridge area.

* TIMING...High tide on the tidal Delaware River occurs between
  2:00 and 3:30 AM Saturday.

* COASTAL FLOOD IMPACTS...Up to one half foot of saltwater
  inundation above ground level is possible in low-lying areas
  near shorelines and tidal waterways. In Philadelphia, roadway
  flooding is possible in the Navy Shipyard, and along Linden
  Avenue, Spring Garden Street, and Washington Avenue. In Delaware
  County, flooding is possible in Tinicum Township. In Gloucester
  and Camden Counties, roadway flooding is possible in Camden,
  West Deptford Township, Gloucester City, and other locations
  near the Delaware River and its tributaries. Minor flooding is
  possible in Bristol, South Trenton, Hamilton Township,
  Burlington City, Delran, and other locations near the Delaware
  River and its tributaries.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Advisory means that minor tidal flooding is
expected. Minor tidal flooding often results in some road
closures. Usually, the most vulnerable roadways will flood.

Do not leave your vehicle at a location that is prone to tidal
flooding. Do not drive your vehicle through flood waters. The
water may be deeper than you think it is. You will be putting
yourself in danger and your vehicle may be damaged, leading to
costly repairs.

Visit the Advanced Hydrologic Prediction Service at
water.weather.gov/ahps for additional water level and flood impact
information for your local tide gauge.
